Oceans cover more than 70% of Earth's surface, making them the world's largest solar collectors. The sun's heat warms the surface water a lot more than the deep ocean water, and this temperature difference creates thermal energy. Just a small portion of the heat trapped in the ocean could power the world.
Current trends in architecture have prevented sustainability from becoming a mainstream design solution and the general population is acutely unaware of the importance of sustainable design. Presently global warming, urban sprawl, and the overuse of natural resources are major concerns for the natural environment. This thesis investigation looks to the future when renewable energy sources may be the only source of power. In addition, designing on the ocean could soon become a reality due to city overcrowding and inadequate natural resource . The design intervention employs ocean thermal energy for a “floating Recreational hub” located 7 Km offshore the coastline of Goa, India. Acting as a self sustaining building, this facility not only uses ocean energy as its primary source of energy, but is also envisioned as an iconic structure which can serve as an educational model for sustainable design, floating architecture, and ocean wave energy
